SkyView HDX Display Installation and Configuration
4-26 SkyView HDX System Installation Manual - Revision E
4.3.11.2 SkyView Audio Output Settings
Go to SETUP MENU > SYSTEM SETUP > AUDIO SETUP to configure audio output
settings. Most of the items in this menu control whether the audio output for a particular
alert or alert category is played or not. The settings that can be adjusted here that are not
voice alert toggles are:
• VOLUME CONTROL / TEST – Sets the volume level. While in this menu, sound
is played continuously so that proper audio connectivity and volume levels can
be confirmed.
o In this menu only, audio is only outputted from the actual display that is in
the setup menu. This allows one (1) to troubleshoot the physical audio
connections. In actual operation, only one (1) of the displays transmits audio
at a time. Which display happens to be transmitting is automatically
managed by SkyView. Since all displays’ audio outputs are connected
together (and to the intercom or audio panel), this is transparent in actual
use.
• BOOT SOUND – When set to ON, the system will say “Dynon Avionics
SkyView” when it first starts up.
• ANGLE OF ATTACK – This sets a pulsing, progressive tone that increases in
frequency, similar in nature to a conventional reed type aircraft stall warning
sound to a reed-type stall warning sound, although it is much more predictable
in its progression. It can be set to start its pulsing tones at either the border of
the yellow/green marks on the AOA bars, the middle of the yellow, or the
yellow/red border. The pulsing tones start at the level selected and get
progressively quicker and closer together until a solid tone is played at critical
AOA (in the red).
o INHIBIT AOA BELOW AIRSPEED – Allows you to set an airspeed below
which no AOA tones are played. This helps prevent nuisance alarms while
on the ground and taxiing, especially in taildraggers.
